studs 7 at the bottom of frame u, perform a similar function on the base-plate f'. These blades 4 and 6 are soton opposite sides, in each instance, of the frame The shafts y ot the beaters carry pinion 7 meshing with pinionr while the bevelpinion s meshes with a bevel-pinion '8 on a shaft 9 journaled in a bracket 10 integral with the cover-plate l; said shaft carries fast and loose pulleysll and 12. The result is that when, shaft 9 is driven its motion is p' transmitted through the bevel pinions t0 shaftj which, rotatin the frame a, causes the pmlons 7 to trave around pinion 1' and be vrotated thereby according to the well.

t and y, is carried by the frame wunder the' pinions r and 7 and approximates very nearly the inside diameter of the inner receptacle so as to very `etlectually isolate the gearing from the cream.

The pipe b comprises the section 13, whereby connection is 'made with afitting 14 connected with cylinder z' by'a union 15; 16is a cap for fitting 14 which may be removed for' the purpose of clearing the passage should the materials freeze or clog therein; this cap may be of glass, if desired, so as to permit l visualinspection of the operation going on f me llnder i.

'l ie base-plate f is formed with an integral spout 17 constructed substantially 'as shown in Figs. 1 and 12, whereby its capacity is very considerable, and pivoted at its mouth, having a' flat surface around it, is a valve 18 and a handle 19, said valve having on its outer face lugs 20 between which the handle extends so that the valve and handle move together.-

21 is a hook into which the handle catches when the valve is closed, and 22l is a setscrew mounted in the handle and adapted to bear against the valve so that, when the valve is in the closed osition, the screw may be employed to jam t e inner fiat face of the 'valve ti htly against the flat face at the month o the s out. Furthermore, the spout being internalll) of rectangular form (Fig. 3), the rightland lower corner portion thereof may be made to coact with the valve, which has a relatively upwa-rd movement, to regulate toa nicety just the size of the cream flow which issues;so that small` molds as well as large may be filled 4in a manspilling. Y,

f ner calculated to avoid overflowing and The cooling medium1 preferably cold" brine, `is circulated around the cylinder z', and for this purpose a spiral partition 23 is introduced between the cylinders z' and j. The .brine enters the space occupied by this partition through a union 24 cast integral with the base-plate f and, after being caused to circulate around the cylinder by the spi-v containing a coil 27 forming a part of a system of piping 28.Which is connected on the one hand with the union 24 and on the other with the port 25; 29 is a pump to keep the brine circulating. In order to increase the e cooling surface of the'coils in the chest 26, two or more of such coils are connected by a reducer 30 with the exterior portion of the system of piping and the coils are refera'bly arranged along one or both sides o the chest 26 and the bottom, leaving a space 31 for the reception of'a block of ice.

In the o eration of the apparatus the mafiterials to e'frozen are placed in hoppera" and, the shaft 9 being driven, thereby cansing the frame u to rotate and the a tators to also rotate in said frame, as descriledQ, the said materials, after being admitted to' the receptacle formed by cylinderszvbase-plate fand the cover structure' from the hopper b opening valve c, are thoroughly agitatedl Meanwhile the pump 29 is voperatedto'drive the brine through the system of piping 28 and through the receptacle -formed by cylinder y', the base-plate and the cover structure. 'lhe brine enters the latter receptacle at the bottom and, by virtue of the partition 23, travels sprally upward around theinnerreceptacle, leaving at the port 25 whereupon,

its tempera-ture having been slightly raised,

it is returned to the coil 27 for recooling.

When the desired conditionV of solidity has been reached, the thumb-serew22-is loosened, thereby )ermitting thevalve 18 'to be raised by handlle 19 s o that .the 'frozen material may be discharged throughthe spout in to a suitable receptacle for that purpose; in order vto assist the dischargy ,the agitating mechanism may'bekept in motion. In the machine illustrated in my co-pending application above referred to, the cream enters the freezing receptacle from the hopper through a central shaft carrying the agitaling means; this lconstruction I lave found to be somewhat impracticable for all Y purposes inasmuch as, if the cream is charged with fruits, the way through the shaft is lili'elj; to heeoine elo Pd, and ii; is not adrisahle to make the saam et suilieientlj; iarge diameter to overcome this diilitruitv. ln the u present, instance, therefore, the pipe leading Lett Patent is:

1. In an ice oreain freezer or the like, the emnhlnat-ion, with a cylindrical receptacle. for the material to he Afrozen, a Cover thereior having a central hollow boss, a `pinion' having a huh exteiuling up into and lined in said hess. a shaft journaled in said pinion axialliY thereof and extending up through the h'oss, means for rotating said shaft lia-V- iney a portion thereof supported by the cover, a traine carried hy said shaft and arranged in said receptacle, agitators journal-,ed in said traine. and pinions earried h v said agitators and meshing with said iirst-named pinion, substantially as described.

ln an irewmnn freezer or the like, the eoinbination of a receptacle lor the nniterial to be frozen, an agitatingv nieehanisin arranged in said reeeptaele. means jfor suppl)L ingI the materials to he lfrozen to the receptacle, and a tubular spout for the discharge of the Jfrozen materials, said spout and the opening from the receptacle affording communication therewith being extended under the bottoni and up the side of the receptacle, substantially as described.

3. The combination, with a discharge spout having a substantially angular formation in the lower inside portion thereof and a iat face around its mouth, of e valve having a flat face adapted to bear against the Hatfaee of the spout, said valve being movable relativelyY upwardly in a plane parallel with the plane of the spout, suhstantially as described.

l. in an iee 'cream freezer or the like, the Combination, with a receptacle for the inaterials to be frozen, of an agitating means inelosed in said receptacle, a discharge outlet for the receptacle, a4 hopper located above the rece Jtacle, a valved 1 e leadino ronr the hopper tothe side of said receptacle near the top thereof and discharging into said receptacle, and a removable Cap arranged in the pipe in alinement with its discharge end, the space of said pipe between its dis charge end and the cap being strzught and free or clear, substantially as described.

in testilnon f. that l claim the forefroinfr I have hereunto set my hand this 14th daf,7 of February, i907.
